A TTORIVEY ornion OTTO RIEKE, OF CHICAGO, ILLINOIS.

SPRING-WINDING MECHANISM.

Application filed March 29, 1915.

To all whom it may concern:

Be it known that I, OTTO RIEKE, a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Spring-Winding Mechanism, ofwhich the following is a specification.

The winding mechanism which is, the subject-matter of the presentapplication for patent is designed more particularly for Winding thespring motor of talking machines, a reciprocatory lever being employedin the place of the usual crank handle.

The invention has for its object to provide a winding mechanism of thekind stated embodying certain novel and improved features ofconstruction and arrangement of parts to be hereinafter. described andclaimed, reference being had to the accompanying drawing in which-Figure l is an elevation of a fragment of a talking machine to which theinvention is applied, and Fig. 2 is a plan view of the windingmechanism.

Referring specifically to the drawing, 5 denotes the box of a talkingmachine in which is housed the spring motor 6 which drives the turntable7 supporting the record disk. The spring of the motor has a windingshaft 8 provided with a suitable pawland-ratchet mechanism 9 to preventthe shaft from slipping back. The outer end of the shaft carries twoclutch members 10 and 11, respectively, the same being disks havingtheir contiguous faces toothed to intermesh, the teeth being arranged totransmit motion in one direction and to slip in the opposite direction.The disk 10 is fast on the shaft, and the disk 11 is loose and slidablethereon. Integral with the disk 11, or separate and made fast thereto,is a bevel pinion 12. A spring13 holds the disks in mesh and yields toallow the same to separate. The spring is coiled around the shaftbetween the bevel pinion and a bearing lat supporting the outer end ofthe shaft.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Serial No. 17,739.

In mesh with the bevel pinion 12 is a curved rack bar 15 connected atone end to a hand lever 16 which is fulcrumed at its inner end, asindicated at 17, to a suitable support in the box 5. The lever and therack bar swing in a horizontal plane. The free end of the lever extendsout of the boX through a side slot 18, and is shaped into a handle 19.

It will be evident from the foregoing that when the lever 16 is swungback and forth, the rack bar 15 rotates the pinion 12 alternately inopposite directions, and when turning in one direction the clutch disk11 of said pinion is locked to the clutch disk 10 and thus imparts arotary movement to the shaft 8 in the same direction. When the pinionturns 1n the opposite direction, no motion is transmitted to the shaftas the pinion slips back and the diskll does not take hold of the disk10, the pawl-andratchet mechanism 9 holding the shaft against slippingback.

I claim The combination with .a spring motor; of a rotary shaft forwinding the motor spring, cooperating clutch members on the shaft, oneof said members being fast on the shaft and the other member being looseand slidable on the shaft, a pinion fast on the lastmentioned clutchmember, yielding means for holding the clutch members locked together, arack bar in mesh with the pinion, and a lever extending in the directionof vthe shaft and connected to the rack bar,

said rack bar extending from one side of the lever, and the latter beingmounted to swing toward and from the shaft.

In testimony whereof I affix my signature in presence of two witnesses.

OTTO RIEKE.
